As Marshall questioned the final decision to stay and be a judge, rather than move the family to Rome, per Lily’s dream…Barney didn’t think that Marshall should be dwelling so much. In fact, he had a very blunt piece of advice.

Now, this “vanquished enemy” in question was Lily – Marshall’s WIFE, so the advice was already flawed. Not to mention, you should always dwell a bit if you think you made the wrong choice and it’s a moral question. (Don’t dwell on whether you should have bought a car in navy blue instead of cobalt, that’s not worth it.)

Maybe you don’t want to take advice from Barney Stinson all the time. After all, he took the saltine challenge. How I Met Your Mother season 9, episode 20. Photo credit: CBS
